Practical Life Activity

This Montessori Practical Life activity is typically used in the 3-6 year old classroom. This material helps develop and strengthen hand and finger muscles of the pincer grip. It is one of the many examples of how the design of Montessori materials indirectly prepare for a future skill – in this case for holding a pencil. In addition, the practical life aspect helps a child to learn how to thread, tighten and loosen a bolt and nut!

The Montessori three bolt block set is an excellent addition to any preschool or homeschool classroom. This activity is both intriguing to children and develops concentration. The set provides a progression of difficulty from easier to harder.
